2 Claini's, '3 Drawing mgn'tas PATENTEDA'PR 16 1974 saw 2 or z 1 CAR STEREO EXPANSION LOCKING KIT FIELD OF INVENTION The present invention relates to demountable brackets for electronic accessories and more particularly to demountable brackets which are provided with locking means.

DESCRIPTION OF THE PRIOR ART bracket members, one intended to be fixedly mounted to the auto, and the opposing bracket intended to be mounted to the player. Demountable brackets may be fastened to the respective auto and player by a variety of fastening means, such as bolts, rivets, and welds. Demountable brackets for auto tape players may also'be provided with locking means. Commonly, the locking means employs various types of shackles and hasps engageable through the mating bracket members. These demountable brackets, having matedbracket members and locking shackles, may be costly and complicated, without adding to thestructural strength and security of the locking bracket. In' practice, it has been found that the bracket member, mounted to the tape player, may impair the use of the tape player for purposes outside the automobile, such as remote tape playing; and may impair the appearance andperformance of the tape player itself.

Accordingly, it is an object of the present invention to provide locking, demountable bracket means for auto electronicaccessories, which employ a fixedly mounted bracket means and a locking lattice independent of the electronic accessory.

It is a further object of this invention to provide demountable bracket means which is visually inaccessible and which may be conveniently locked and unlocked with a key. r

These and other objects shall become apparent from the description following, it being understood that modifications may be made without affecting the teachings of the invention here set out.

SUMMARY OF THE INVENTION Generally, the car stereo expansion locking kit comprises a plurality of cornerposts operable to closely, slidably receive a car stereo, or the like, and having a plurality .of horizontally cut lattice receiving slots, a,

locking lattice including a plurality of rectilinear and transverse lattice strips pivotally mounted at intervals to each otherto form a parallelogramand including a pair of diagonally disposed, slot-engaging leaves fastened at diagonal corners of the locking lattice, and a lock operable to selectively lock the locking lattice into the slots of the cornerposts.

A more thorough and comprehensive understanding may be had from, the detailed description of the preferred embodiment when read in connection with the drawings forming a part of this specification.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 2 is a bottom plan view of the locking latticeand lock of this invention shown as it would appear in its unlocked position.

FIG. 3 is a bottom plan view of the apparatus of the FIG. 2 shown as it would appear in the locked position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and more particularly to the FIG. 1, the car stereo expansion locking kit of this invention is shown to advantage and generally identified by the numeral 10. The expansion lock 10 comprises aplurality of cornerposts 11, a locking lattice l2, and a lattice lock 13. The cornerposts 11 may be fabricated of angle iron-like members, and may be fastened upstandingly to a vehicle (not shown) by means of bolts, rivets and the like (not shown) engageable through bolt brackets 11 provided at the interior corner at the uppermost terminal end of each of the members 11'. Each of the posts 11 are fastened with their vertical corners disposed away from the geometrical center. of a substantially rectangular region which is operable to closely receive a car'stereo 14 and similar accessory equipment. A plurality of horizontally cut, distally disposed slots 15 are provided from the vertical corner edge into the side walls of the cornerposts 11.

The slots 15 are operable to engage locking leaf portions 16 of the locking lattice 12. The locking lattice 12 comprises a plurality of rectilinear lattice strips 17 and 17' and transverse locking strips 18 and 18. A pair of rectilinear lattice strips 17 and a pair of lattice locking strips 18 are parallelly, pivotally fastened to the respective terminal ends of each of the strips 17 and 18. The rectilinear middle lattice strip 17' is pivotally fastened at its terminal ends midway on the transverse lattice strips 18; and the transverse middle lattice strip 18' is pivotally fastened'at its terminal ends midway on the rectilinear lattice strips 17 and at its midpoint to the midpoint of the middle lattice strip17l Thus, it may be seen that the locking lattice, comprising the lattice strips 17, 17, 18 and 18', is operable to form a pivotally fastened parallelogram. The locking leaves 16 are fastened at a pair of 'diagonal corners of the pivotally fastened intersects of the lattice strips l7'and 18. The locking leaves may have a pointed configuration operable to engage suitable horizontal pairs of the slots 15of the cornerposts 11. It is to be understood that while all the cornerposts 11 are provided with slots 15, the expansion lock 10 of this invention may be satisfactorily fabricated with slots 15. included in a pair of diagonal cornerposts ll. v

The lattice lock 13 is intended to selectively lock the lattice 12 into a predetermined locked juxtaposition. The lattice lock 13 comprises a body member 19, a pair of dogs 20, and a cylinder 21.. The dogs 20 are a pair of substantially C-shaped members, and are car-. ried opposingly to each other on the body member 19. The locking dogs 20 are actuated and locked by means of a substantially commonly known locking cylinder 21 disposed between thedogs 20 in the body member 19.

The lattice lock 13 is operable to lock the. lattice 12 by engaging the intersect of the lattice strips 17' and 18' on a geometrical diagonal perpendicular to the diagonal of leaves 16.

3 4 In operation, a car stereo 14 may be slidably disposed bolt bracket provided at the interior terminal corwithin the cornerposts 11. As shown in the FIGS. 2 and ner of the uppermost terminal ends of said angle 3, the locking lattice 12 is conformed to a substantially iron-like members, and a horizontal slot cut into rectangular configuration and is disposed adjacent the the vertical comer of angle iron-like member of a lowermost terminal side of the car stereo 14. The latdiagonal pair of said cornerposts; tice lock 13 may be disposed diagonally at the intersect a locking lattice including a pair of rectilinear lattice of the strips 17 and 18 with the edges 20 disposed in strips pivotally fastened at each of their terminal their outermost position. The lattice 12 may then be ends to the terminal ends of a pair of parallelly disconformed into a parallelogram with the locking leaves posed transverse lattice strips, a rectilinear middle 16 disposed through a suitable, horizontal slot 15 in lattice strip being pivotally fastened at its terminal each of a diagonal pair of cornerposts 11. By actuating ends midway on said transverse lattice strips, a the locking cylinder 21 and simultaneously locking the transverse middle lattice strip being pivotally fasdogs 20 to their closed position, the lattice 12 is setened at its terminal ends midway on said rectilincured into a locked, substantially stable configuration ear lattice strips and at its midpoint to the midbeneath the car stereo 14. point of said rectilinear middle lattice strip, and a Having thus described in detail a preferred apparatus pair of locking leaf portions, said locking leaf porwhich embodies the concepts and principles of the intions being operable to engage said cornerpost vention and which accomplishes the various objects, slots, said locking leaf portions being fastened at a purposes and aims thereof, it is to be appreciated and pair of diagonal exterior corners of said locking latwill be apparent to those skilled in the art that many tice; and physical changes could be made in the apparatus witha lattice lock including a body member, a pair of dogs out altering the inventive concepts and principles emincluding a pair of substantially C-shaped members bodied therein.
